Output
The output stage consists of complementary P and N
channel devices connected to provide railtorail output
drive. With a 2.0 k load, the output can swing within 50 mV
of either rail. It is also capable of supplying over 75 mA
when powered from 5.0 V and 1.0 mA when powered from
0.9 V.
When connected as a unity gain follower, the NCS2002
can directly drive capacitive loads in excess of 820 pF at
room temperature without oscillating but with significantly
reduced phase margin. The unity gain follower
configuration exhibits the highest bandwidth and is most
prone to oscillations when driving a high value capacitive
load. The capacitive load in combination with the
amplifier’s output impedance, creates a phase lag that can
result in an underdamped pulse response or a continuous
oscillation. Figure 35 shows the effect of driving a large
capacitive load in a voltage follower type of setup. When
driving capacitive loads exceeding 820 pF, it is
recommended to place a low value isolation resistor
between the output of the op amp and the load, as shown in
Figure 34. The series resistor isolates the capacitive load
from the output and enhances the phase margin. Refer to
Figure 36. Larger values of R will result in a cleaner output
waveform but excessively large values will degrade the
large signal rise and fall time and reduce the output
amplitude. Depending upon the capacitor characteristics,
the isolation resistor value will typically be between 50 to
500
W. The output drive capability for resistive and

Input
Note that the lowest phase margin is observed at cold
temperature and low supply voltage.
Enable Pin
The enable pin allows the user to externally control the
device. if the enable pin is pulled below the input disable
threshold voltage (VEN < 45% VCC), the amplifier is
disabled. Once the enable pin is taken above the threshold
voltage (VEN = 60% VCC), the amplifier will turn on. In the
event the enable pin is not connected, the amplifier will
remain on by default
